To all whom it mdj concern Be it known that I, HENRY R. BENSON, acitizen of the United States of America, and resident of the cityofSedro-Woolley, Skagit County, State of Washington, have invented certainnew and useful Improvements in Choker Hooks, of which the following is aspecification.

My invention relates to hooks such as are used in logging and landclearing operations and which are known as choker hooks.

The principal object of my invention is to provide a choker hook fromwhich the line will not slip when slackened;

Another object of my invention is to provide such a choker hook withwhich the line may be easily engaged and which is without latches orother movable and breakable parts;

- My invention 'c-omprisesthose novel parts and combinations andarrangements thereof which are shown in'the accompanying draw ings,described in'the specification, and particularly defined by the claimsterminating the same. I

In the accompanying drawings I" have shown my invention in the form'whichis now preferred by me. 7 c

Figure l is an elevation of my hook with a line shown in place'ther'ein. V

F'gure 2 is an elevation of the same hool and line, taken at rightangles to Figure 1.

Figure 3 is a section through the shank of the hook near the bend,lookingtoward the eye. 5

Figure 4 is a attached to a log.

Choker hooks such as my invention relates to are secured upon the end ofa choker line 1, as shown in Figure 4. The line passes from the eye ofthe hook about a log which is to be drawn oif by the line, and thenpasses through the bend of the hook, and thence to a hauling line. Suchhooks will hold readily while a strain is on the line, but if the chokerline 1 is slackened the hook is easily and often accidentally disengagedtherefrom. Hooks have been provided with latches and other means ofpositively locking the line in the hook, but these devices are noteasily operated, either in securing the line or releasing it, they addgreatly to the expenseof the hook, and they are easily broken with therough usage to which they are subjected.

' By my invention I propose to provide perspective of my device'oHoKEn'HooKg 192 1. seriaiivo. 473,986.

simple means in nn tion with the ag nary type of choker hook which willpermit thelineto run readilythrough'the hook under the strain, butwhich-will grip the line when the latter is slackenedto prevent releaseof the hook therefrom iln most re,

spect s the hook may be similar to the choker hooks now in use." It isprovided with, an

eye 2, a broad shank 3,ben :l 4, and point, 5,

which are similarly arranged as in the ordlnary chokerhooks. 'The point5" may depart slightly from the usual design in that t is slightly morepointed, as may. be seen in Figure 1. j i

Adjacent the side edges of the shank 3 and adjacent the bend el-"Of thehook, I provide a pair oflugs '6. These lugs rise from the shank towardsthe point5' and are provided \vitlrshou'lders 7 which facetewards thebend 4L.- Thecentral*portionf*8 of the bend a, lying between the side:edges of the hook, is projectedtowarcls the general plane of the twoshoulders? Thereis thus formed between the shoulders 7 andthe'centralportion 8 of the bend, cable-receiving passage which, for the size ofcabl 'j t n r point 5 of the hook, as shown in full lines in Figure 4.Upon being placed under tension, the drag of the log 9 will cause thecable to be drawn into the bend of the hook andto be, engaged under theother shoulder 7 as shown in dotted lines in Figure 4.

So long as the line 1 is under tension it will bend about the portion '8of the bend, and being thus drawn away from the shoulders 7, it-inay runfreely through the hook. lVhenthe tension on the cable is relieved andon account of the inherent stifi'ness'of the cable, the line will, inslackening,-engage the shoulders '7; Being kinked as shown in Figure 1,it will be firmly held so that it may not run further through the theshoulders 7, they may be corrugated as shown in FiguresQ' and 3 tocorrespond to the strands of the cable employed, These corrugations willassist in the gripping ac-v same material as the hook, and integraltherewith, areas strong as the hook itself,

andare not liable to be broken oil in use. They ofi'er no surface whichmight be caught 'by roots or branches, whereby the hook might beentangled or the choker line broken. V

j lVhat I claim as my invention isi 1. A choker hook having atransverselyeXtending cable-receiving. passage therethrough at its bend,and sinuous in a plane substantially parallel to the hook shank, theentrance to said passagefrom the point of the hook being open and of asize to permit free entrance of a cable therethrough.

2. A choker hook having a sinuous transversely-extending cable-receivingpassage therethrough at its bend, the entrance to said passage from thepoint of the hook be-v ing open to permit entrance of a cable and curvedboth transversely and longitudinally of the hook.

3-. A choker hook having lugs with cable engaging surfaces facingtowards the bend of the hook, and located at the side edges of its shankadjacent the bend, a portion of the hook at thebend between its sideedges being projected towards the general plane of said cable-engagingsurfaces, to form with said lugs a sinuoustransversely-eartendingcable-receiving passage, the entrance to said passage from the point ofthe hook being unobstructed and of a size to permit entrance of a cabletherethrough.

a. A choker hook having lugs projecting at each side of the body intothe space between the hook body and its point, the inside tace of thehook point being conveXly rounded transversely and the edges of saidlugs being spaced away from the adjacent side edges of the hook point topermit passage of the rope, the ends of the lugs towards the bendof thehook being shouldered to permit the rope to be seated thereunder; r r

5. A choker hook having lugs projecting from the face ofits bodywwhichfacesftoward the tip of the hook, said lugs being separated to beoutside of the sideimar ginal lines of the hook tip and having theirends which are towards the bend of the hook shouldered vQto receive theline thereunder. 1

6. A choker hook having a broad fiat shank and flanges along the sidemargins of the shank extending into the space between the shank land thehook tip, said flanges terminatinga short distance inward from thebottom of the hook opening to form shoulders transversely alinedwith'the bottom of said opening-the hook tiphaving a transversely curvedinner face the central longitudinal line of which approaches near enoughto the plane ofthe outer faces of the flanges to requireybending oftheline when inserting or removing it.
